HAM-BOILEB.

Application filed September 5, 1917.

To all 'whom t may concern:

Be it known that I, HANS Anmnxxx, a subject of the Emperor of Germany, and resident of the city of New York, borough of the Bronx, county of Bronx, and State of and Improved Ham-Boiler, of which the following is a full, clear, and exact description.

This invention relates to meat cooking appliances and has particular reference to ham boilers or the like of the general type covered by Letters Patent of the United States issued to the Ham Boiler Corporation on October' 24, 1916, No. 1,202,637, November 21, 1916, Design No. 49,915, and November 28, 1916, No. 1,206,494.

Among the objects of this present improvement is to render a ham boiler more convenient with respect to the manipulation of the meat and much more rapid with respect to the means for inserting and removing the meat.

Another object of the invention is to relieve the machine from certain awkward or cumbersome extensions that obtain in the previous machines proposed for this puriose.

lVith the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had tov the accompanying drawing, which is a ver-tif cal central longitudinal section showing the vcomplete apparatus in full lines with the cap located just within the main receptacle and indicating in dot and dash lines the position of the cap and locking dogs when under maximum collapse or contraction.

Referring now more particularly to` the drawing, the body 10 is of any suitable form adapting it to receive a ham for molding and cooking the same and to impart to the cooked ham an appearance of having been Wrapped with a cord while being cooked, as has beenset forth in my previous patents. The body 10 in this instance is formed with longitudinal ribs 11 along its closed bottom serving as means forsupporting the saine in erect position. At each end of the body is formed a rack 12 having transversely arranged teeth, the points -of which project Specification of Letters Patent.

outward and downward preferably in the I prefer to form this portion of the device as a single casting of aluminum or other suitable metal including the racks.

. A cap portion 13 constituting a slidable closure for the body includes a substantially flat top portion v1-1 and a downwardly projecting skirt or flange l5. The side portions of the flange 15 are preferably tluted to correspond and coperate with the ribs 16 projecting into or toward the center of the body. The inner surface of the top 1l is also preferably provided with a sufficient number of transverse ribs 17 to stitfen this part of thedevice, said ribs also being made with sharp edges, serving to bite more or less into the ham or other piece of meat and hold the skin or wrapper that may be used thereon from slipping. The upper face of the cover 13 is provided with a pair of upwaJrdly projecting bosses 1S preferably formed integral with the cover and each provided with a central tapped hole 18f having a vertical axis.

The third main portion of the machine consists of a bar 19 approximately straight along its lower face and more or less convexed longitudinally along its upper edge or face. This bar is'formed at its ends with a pair4 of knuckles 20 having transverse parallel holes 21, the knuckles extending somewhat below the plane of the main portion of the bottom of the bar. The crossbar in length is slightly greater than that of the body 10, the vertical planes of the centers of the holes 21 being just beyond the planes of the points of the teeth in the racks 12. The bar is provided with a pair of downwardly projecting bosses 22 having smooth central holes 22', the upper ends of which merge into enlarged openings 23 at the top of the bar. The end portions 24 of the bar between the openings 23 and the knuckles may be more or less rounded to serve as handles in manipula-ting the device.

25 indicates a rigid dog having a hook or tooth 26 at its lower end adapted to engage beneath any one of the teeth of the rack 12. The upper end of the dog is hinged by means of a pivot pin 27 to the knuckle 20, the pin passing through the transverse hole 21. This description of the dog at one end of the bar applies to that of the other end of the bar.

` Each of the bosses 22 is arranged in version Aupon the raw ham when tical alinement with but spaced from one of the bosses 18 and a. strongspiral spring 28= is seated at one end around one boss and at the other end around the other boss. l The tendency of these springs is to force the cap or cover 13 downward and the bar'upward with .respect to each other. This tendency of t e springs is resisted by a pair of screws 29 littjed loosely through the holes 22 of the bosses 22 and fixed in the threaded holes 18 of the lower bosses, the heads 30 of the screws lying normally against the bottoms of the openings 23 within the bar. These springs and pins are so designed as to limit the `expansive action of the springs while the springs are under some suitable degree of compression, such compression being regulatable by screwing the screws more or less deeply into the holes 18.

The operation of this device may be briefly summarized as follows in view of the foregoing specific description: After the ham is made, as the process is called in practice'7 by boning and trimming and arranging the skin or wrapper thereon, it is plunged into the interior of the body 10 and the cap isl then forced down upon the same with a 28, but limited by the opposing bosses 1'8 and 22 while the screws are adapted to slip up; through the bar. The manipulation of this device,'therefore, is exceedingly rapid inasmuch as the operator, by bearing down upon the bar', is able toapply sutlicient compreslpreparing the device for the cooker. At the same time the natural expansion of the ham, during the cooking action, is amply provided for b'y the compressibility of the springs. The operator having his hands at the handles 24 may easily manipulate the dogs to either swing vthe dogs 25 normally swing by nected therewith, of

them in or out as may be necessary by the planes of the pivots beyond they vertical planes of the teeth it will be noted that w en thebar is depressed gravity away from the teeth, thus facilitating the removal of the cover. I claim:

1. In a ham'boiler, body receptacle having formed as an integral part of each .end a vertical series of rack teeth which project outward and downward, a cover for the receptacle telescoping therewith., a bar having ends projecting over and beyond the vertical planes of the racks the combination of a the bar and having hooked coperation with Y the rack teeth to hold the bar in fixed ad- ]usted position with respect to the body,

and resilient means interposed between the cover and the bar.

2. In a ham boiler, the combination with a receptacle and a cover telescopically cona bar'extending above the cover and longitudinallyof the same and the receptacle, members pivoted to the ends ofl the bar and coperating with the ends ofthe-receptacle to hold the bar from upward movement, a pair of bolts connectedto the] cover and, slidable through the bar and serving to limit the' extent ofrelative separation of the bar and cover, and a pair of springs acting between the cover and the bar tending to prevent relative movement of the cover and bar toward each other.

3. In a ham boiler, the combination with a receptacle and cover telescopically connected therewith, of a bar extending above and longitudinally of the cover, a pair of bolts extending between the bar and the cover and fixed to one of them and slidable through the other, a pair of springs between the'bar and the cover tending to keep the cver andthe bar separated as far as will be permitted by the bolts, and means to lock the cover and bar to the receptacle.
